We demonstrate a cost-effective, highly reliable/stable and environmentally friendly approach for the patterned colouring of commercial transparent polyethylene terephthalate (PET). show that different colour patterns (transparent, white/translucent, complete white/silver combinations these three colours) can be realised in PET strips upon varying speed during continuous stretching. The conditi...

Solar water disinfection (SODIS) is a simple, effective and inexpensive water treatment procedure suitable for application in developing countries. Microbially contaminated water is filled into transparent polyethylene terephthalate (PET) plastic bottles and exposed to full sunlight for at least 6h. Solar radiation and elevated temperature destroy pathogenic germs efficiently. Recently, concern...

Two different procedures of grafting with silver nanoparticles (AgNP) of polyethylene terephthalate (PET), activated by plasma treatment, are studied. In the first procedure, the PET foil was grafted with biphenyl-4,4'-dithiol and subsequently with silver nanoparticles. In the second one, the PET foil was grafted with silver nanoparticles previously coated with the same dithiol. X-ray photoelec...

Low-resistivity indium tin oxide [ITO] film was successfully deposited on oxygen plasma-treated polyethylene terephthalate [PET] surfaces at room temperature. X-ray diffraction [XRD] measurements demonstrated that the film deposited on the PET surface that had not been treated with oxygen plasma had an amorphous structure. In contrast, after the low-power oxygen plasma treatment of the PET surf...

This paper studies the relationship between crimp curvatures and elastic strains of two series of PTT (Polytrimethylene terephthalate)/ PET (Polyethylene terephthalate) self-crimping fibers produced with two different spinnerets which merge PTT and PET fluids at different points. The crimp curvature is estimated based on fiber crosssectional parameters and the polymer properties. The elastic st...

The use of 3D printers for manufacturing processes comes with the challenge filament replacement subsequent processes. This aforementioned including environmental problems posed by plastics wastes formed basis current work which is focused on design and construction a simple single extruder production filaments from waste polyethylene terephthalate (PET) rapid prototyping machines printers. Thr...

Shape memory properties of PET (polyethylene-terephthalate) foams have been evaluated for two different foam densities. Samples were subjected to multiple memory-recovery cycles along three different directions to measure the effect of foam anisotropy on static mechanical and shape memory properties. The memory cycle was performed by uniaxial compression tests at room temperature. Despite these...
